Aether Walker is a Legendary Wand for the Wizard in Diablo III. It requires character level 70 to drop, and originally only dropped during the Season One for Seasonal characters. After the end of the Season One, it drops for normal characters as well. The unique property removes the cooldown of Teleport (technically, reduces it to 0.5 seconds), replacing it with a (quite considerable) Arcane Power cost, making the spell function more like the classic version. As of patch 2.3.0, this effect works with Archon Teleport spell as well, removing its cooldown, but not adding any cost.
